SAFETY REQUIREMENTS AND PROTECTIVE REGULATIONS
6.1
EMC
Since the MBa8MPxL is a development platform, no EMC tests have been performed.
6.2
ESD
Most interfaces provide ESD protection. Details are to be taken from the MBa8MPxL schematics.
6.3
Operational safety and personal security
Tests for operational safety and personal protection were not carried out due to the voltages ≤30 V DC.
7.
CLIMATIC AND OPERATIONAL CONDITIONS
In general reliable operation is given when the following conditions are met:

Attention: TQMa8MPxL heat dissipation
The i.MX 8M Plus belongs to a performance category in which a cooling system is essential.
It is the user’s sole responsibility to define a suitable heat sink (weight and mounting position)
depending on the specific mode of operation (e.g., dependence on clock frequency, stack height,
airflow, and software).
Particularly the tolerance chain (PCB thickness, board warpage, BGA balls, BGA package, thermal pad,
heatsink) as well as the maximum pressure on the TQMa8MPxL must be taken into consideration
when connecting the heat sink.
The TQMa8MPxL is not the highest component. Inadequate cooling connections can lead to
overheating of the TQMa8MPxL or the MBa8MPxL and thus malfunction, deterioration or destruction.
7.1
Protection against external effects
Protection class IP00 was defined for the MBa8MPxL. There is no protection against foreign objects, touch or humidity.
7.2
Reliability and service life
No detailed MTBF calculation has been done for the MBa8MPxL.
The MBa8MPxL is designed to be insensitive to vibration and impact.
